(please refer to page 4)


WARNINGS

 The use of filters other than those supplied by Purex or an authorised agent will invalidate any warranty, service contract and any LEV certification !

  • Always isolate the system from the mains power supply before opening any doors or lids.
  • Disposable gloves and a dust mask are supplied with replacement filters. they should be worn when removing Dispose used filters in the bag provided
  • Filters are manufactured from non-toxic materials.
  • Filters and prefilters are not re-usable and no attempt should be made to clean them.
  • Used filters and prefilters should be disposed of in accordance with local laws and regulations. The company and its agents disclaim all liability and responsibility for any harm, damage, contamination or injury caused by inappropriate or unlawful disposal.
  • Purex systems use high pressure pumps, which may cause inferior filters to burst, allowing hazardous fumes into the Do not use filters that have only been tested to BS3928, BS5295 or AS208C as these standards are flow checks only and are designed to test filters used in general dust extraction and air conditioning.
  • Consult the local regulations concerning fume extraction systems, as these may be subject to requirements including; periodic checks by authorised agencies, re-issue of certificates of compliance or equivalents etc. Consult your supplier if in doubt.
  • Consult your supplier for information on maintenance agreements that will ensure conformance to local regulations.

 

Schedule

Primary maintenance is filter replacement, the machine control system will indicate when this is required. Filters should be replaced annually as a matter of course.

To ensure the smooth running of the extraction machine and associated equipment, please perform the following periodic checks:

Daily                 – Visually check that the fumes are being drawn into the extraction point

– Check the status of the display screen

Annually          – Change filters and consult your supplier for maintenance checks and/or certification

 

Positioning the machine

The machine should be as near to the process as possible with space allowed for the following access:

  • Internal maintenance
  • Control panel, replacing filters
  • Exhaust air + cooling air, electrical connections, hose connection Once in position, lock the two front castors by depressing the foot levers.

Hose connection

Incorrect connection or layout of hose can cause poor airflow, blockages and potentially dangerous build up of fume. Use the shortest length of hose possible and keep bends to a minimum. Your supplier can advise you of appropriate diameters and layouts of hose for your particular application.

  • It is best practice to use the connection kit supplied.
  • The use of small diameter pipe / hose or nozzles can reduce the performance of fume extraction systems and so should be avoided
  • If a special connection kit or attachment is required please contact Purex or your local agent.

Ensure all connections are properly sealed and that there are no kinks in the hose. Once secured in position, connect the hose/s to the inlet/s on the machine either by pushing the hose onto the inlet or by using the connections supplied.

Electrical connection

Various connection methods are available to order. Prior to connecting the power supply, ensure that the voltage, frequency and power requirements are correct as shown on the label attached to the cabinet rear ( Note – these are MAX values). It is important that the local supply is protected by a circuit breaker of the correct rating, and that the cabling and plug type used are similarly rated. Ensure the plug is accessible as a disconnect device.

For 800/800i series machines it is advised that a rotary isolator switch is used as a power disconnect device.

Interface Socket

When not in use this socket is protected by a screw-on cap.

Interfacing

To enable interfacing unscrew the interface socket cap and plug in the interface cable or remote ON/OFF switch. Connect the other end of the interface cable or remote ON/OFF switch to your related machine. Please note there is only one interface socket so an interface cable and the remote ON/OFF switch cannot be used together.

Warning

Use of unapproved cables or interfacing connections may invalidate your warranty.

ENSURE ALL FILTERS ARE FITTED CORRECTLY PRIOR TO USING THE MACHINE.

DO NOT LIFT THE FILTERS USING THE HANDLES, THESE ARE ONLY TO BE USED FOR SLIDING THE FILTERS OUT OF THE MACHINE.

Important note:

Always check the extraction nozzle, flexible hose, pipework and the air inlet for debris build up before changing any filter. This avoids false alerts related to airflow.

Replacing filters

The touchscreen will display “Order Main Filter” and/or “Order Pre-Filter” when the filters are partially blocked, please contact your supplier to order filters.

The touchscreen will then display “Replace Main Filter” and/or “Replace Pre-Filter” when the filters are blocked, change the filters immediately.

Changing filters

The machine will warn you with audible and visible alerts if a filter is exhausted (see warning and alarm signals). The display will flash the icons of the filters which need attention. Take care when removing main filters as they are heavy. Always wear the protective gloves and mask provided and dispose of used filters in the bag provided. Protective eyewear should also be worn when changing filters.

Opening the filter compartment door

  • Ensure your process is stopped
  • Switch off your Purex machine at the control panel (see Touchscreen control system)
  • Turn the door lock/s on the front of the filter compartment door
  • Open the door

Changing the pre-filter

200/400/800 – Always change the pre-filter first (unless recently changed) and restart the machine. If the alert continues, change the main filter. To remove the pad, first remove the main filter and turn it over (See Changing the main filter). Remove the pad and replace it with a new one. Make sure the harder, smoother side of the pad is facing the main filter. Turn the filters the correct way round and place back in to the extractor. (See picture “Pre-filter pad” above).

 

200i/400i/400i PVC/300i/800i – All have Labyrinth pre-filters which can be removed by pulling the filter off the air inlet inside the machine before replacing with a new one. 400i PVC machines also have an adsorbent pad in the base of the machine underneath the Labyrinth filter. This should be replaced at the same time as the Labyrinth filter. It is also good practice to wipe the inside of the machine periodically with a cloth to avoid build up of liquid. Suitable protective clothing should always be worn.

 

Changing the main filter

  • Open the door
  • Turn the filter locking handle (5) 180° anti-clockwise so that it is horizontal and in the filter unlocked position
  • The filter (3) should drop slightly to allow release
  • Remove the filter by sliding it towards you and remove it completely from the machine
  • Insert the new filter (completely) into the machine ensuring that the airflow arrow on the label (6) is pointing up
  • Turn the filter locking handle 180° clockwise so that it is horizontal and in the filter locked position
  • Close and lock the door and restart the machine

 

Notes: The 800i 3-tier has two main filters, always ensure you are replacing the correct one.
